1s1 Energy
1s1 Energy is a materials-science company making green hydrogen cheaper by rethinking the guts of the electrolyzer. Instead of the fluorinated (PFAS) membranes the industry has leaned on for decades, 1s1 builds boron-based proton-exchange membranes and electrochemical components that its partners report can produce a kilogram of hydrogen using roughly 70% of the energy of incumbent devices - already hitting efficiency targets the U.S. Department of Energy set for 2031. Founded in 2019 and run out of Portola Valley, California with labs in Lisbon and Campinas, Brazil, the company sells core components to electrolyzer and fuel-cell makers and runs pilots with utilities and heavy industry.

Daniel Sobek is the co-founder and CEO of 1s1 Energy, a Portola Valley startup turning a chunk of boron chemistry into cheaper, cleaner green hydrogen. An MIT-trained engineer with three degrees from the institute and a habit of starting companies, he spent years in microfluidics and cancer-imaging hardware before betting on electrolyzers. His company's boron-based membranes claim to cut the energy needed to make hydrogen by about 30 percent, and he says they already hit a U.S. Department of Energy efficiency target set for 2031.
